Apical dorsal seta of femur brown, moderately long, basodorsal seta 

 slightly larger; anterior seta short, strong, situated subventrally in basal 

 part about in middle of segment; primary ventral setae situated more 

 apically, in form of a light, thick, moderately long, apical spine-shaped seta 

 and an adjacent large, yellowish, blunt spine; posterior seta situated 

 basal to spines, dark brown, moderately long (Figure 200, A); anterior 

 surface with a small, brownish, secondary seta in apical area, and 2 similar 

 setae in basal area. 



Primary dorsal and subdorsal setae of tibia situated in pairs apically 

 on posterior side and subapically on anterior side; more basally on dorsal 

 surface, 2 long, brown, secondary setae longer than primary setae of 

 femur and coxa; other secondary setae consisting of 2 small, light, dorsal 

 and 4 subdorsal setae, 2 of them situated posteriorly, 2 anteriorly. On 

 tarsus, in addition to primary setae, a long, brown, secondary, dorsal 

 seta, slightly smaller than that on tibia; remaining 4 secondary setae 

 thin, light, small. Basal seta of claw light, large. 



Basodorsal seta, and one of the mid-coxa secondary dorsal setae long; 

 posterior distodorsal seta the same; 5—7 secondary marginal setae, including 

 1—2 similarly long seta, more distally on posterior side; 3—4 anterior 

 distodorsal setae, including a moderately long primary seta. Anterior 

 seta of trochanter yellowish, short, thick; posterior seta short, dark, thin; 

 basoventral seta grayish, thick, long; primary ventral setae in form of 2 

 light spines, the basal spine nearer the suture than on forelegs; both long 

 posterior ventral setae situated close together; 3 posterior, secondary 

 setae short. Basodorsal seta of femur moderately long, larger than apical 

 ventral seta in form of light, thin, short spine in middle of segment; 

 basoventral seta brownish, thick, moderately long (Figure 200, B). Tibia 

 with a very long,thick,brown, secondary seta dorsally inthe middle, the longest 

 seta of midlegs; primary distodorsal seta and 2 secondary dorsal setae
